Adding shopping cart to site

I wish to add a shopping cart to my hunting site www.teamlastflight.com. On the upper left-hand side of the site you will see the outline of a duck's head and below it it says hunting apparel and gear for sale. I want to replace that image with a picture of some teamlastflight apparel and make it link to a new page that has items for sale. To start I will have three different shirts and two different hats that I will sell, but the site needs to be scalable to add more in the future. I want to be able to accept credit cards and Paypal and obviously be notified in some way that an order has been placed. Currently the site is a static html site.
